Which of the following phases does the cell have TWO nuclei?
A
telophase
B
anaphase
C
metaphase
D
prophase
Explanation: 

Detailed explanation-1: -Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

Detailed explanation-2: -During telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same cell.

Detailed explanation-3: -Hence, the cell at telophase has two nuclei.

Detailed explanation-4: -Telophase I: The chromosomes are now at opposite ends of the cell and begin to form two distinct chromosome clusters. At this point, nuclear division begins, and the parent cell is divided in half, forming 2 daughter cells.

Detailed explanation-5: -In telophase II, the cells divide, new cell walls are formed and there are four haploid cells. These four cells are called a tetrad. In telophase II, the cells divide, new cell walls are formed and there are four haploid cells. These four cells are called a tetrad.
